How to use the tier list without overbuying
The Animal Hospital classes tier list should answer one question first: which class helps your current run? A solo player needs reliability and simple recovery. A team needs role coverage, inventory planning, and someone who can watch for strange room behavior while another player handles treatment.
Surgeon appears as the safest high-value recommendation in the current research because treatment pressure is central to many runs. Head Nurse can matter for inventory flexibility, especially in teams, but any paid or Robux-linked class should be judged against your playstyle and the current live game cost.
